WATER-METER.

Specification of Letters Patentv No. 12,934, dated May 22, 1855.

To all whom t may concern:

' Be it known that I, J. S. BARDEN, of the city of New Haven, in the county of New Haven and in the State of Connecticut, have invented a new and Improved Mode of Constructing Water-Meters; and I do hereby declare that the following is a full and eX- act description of the same, reference being had to the accompanying drawings and letters and gures of reference marked thereon. Figure 1, plate l, represents a perspective view of the base in which the working parts of the machine is contained. l, l, are heads, secured to each end of the case by means of bolts or screws which are to be removed when repairs or examination is necessaryof the cylinder, piston, or other parts of the machine or the removal of sediment that may collect upon the sides and bottom in sufficient quantities to interfere with the operation of the machine save the slide valve a Fig. 2 which is examined by removing the cover 2, which is secured by boltsl or screws to the top of the valve chest 3 which acts as a reservoir to receive the water from the fountain head, through the opening 4. Fig. 2, plate 1, represents a perspective view of the case with both heads removedl l and one side. Also the top of the case, with the valve chest cut into through the center with the cover 2, removed entirely, showing the entire construction of the machine. Fig. 3, plate l, represents a longitudinal section of the case, and machinery. Fig. 4, plate l, represents a cross section of the case showing the slide valve a ingress and egress openings 4 and 5. Fig. 5, plate 2, represents a cross section of the case showing the cylinder B flanch D connected to the same passing around the cylinder in the center, as to length or near it. Also the arm and thimbles for moving the slide valve a, piston E, and partition lL0. y

This case is divided into two equal proportions or compartments see Fig. 3 through the center vertically by means of the partition b. Each compartment having no connection with each other save through the opening in the center of the partition, 7 Fig. 4 which is closed by the cylinder B passing through the opening, and secured inthe center of the case equidistant from each end, and permanently by means of bolts or screws passing through the flanches D, and partition b having a leather or india rubber washer between them to form a perfect joint, the cylinder being open at both ends, the case with its heads being' thus divided and an open cylinder at both ends and suspended in the partition equidistant from it on both sides acts in the capacity of heads to the cylinder, also a reservoir to receive all sediment that may pass from the valve chest into the case and cylinder to either of the passages H, I, and does not pass out or the collection of sediment deposited from the water upon its sides, by which arrangement all forms of stuiing boxes complication of springs and other machinery as is connected with other cylindrical water meters are done away with.

E, E, represents two piston plates, with the ordinary cup leathers to form the packing, one turned toward the left, the other toward the right and lboth with the pac-king leathers screwed together with a bolt having no form of piston rod connected with them.

F, F, represents one single groove cast or turned. Upon the 'circumference of each plate Gr, G, are holes drilled through the ianches of the plate from the base of the groove-thereby forming a passage for a current of water to pass around the same :and press upon the inner surface of the leather piston. Thereby as the piston traverses from left to right and vice versa and by such means the pressure of the water passing through these holes into the grooves onto the inner surface of the leather packing, causes it to hug the cylinder making 4the same perfectly tight till it is entirely worn out.

H, I, are two passages-one passing into each compartment-to permit the water to pass from the valve chest 3 to cause the pis- `ton to traverse the cylinder and out alternately through the egress passage and opening J5, as the slide valve covers one or the other.

a, is the ordinary slide valve, which covers the egress passage J and one ofthe ingress ones alternately.

D, represents a separate composition valve seat for the slide valve to traverse upon-having' openings to correspond with the two ingress and one egress passages, also the openings g, g, and is secured in its place by means of screws.

L1 L2 are two hollow thimb-les one slipping within the other-having a spiral spring m m within them, one thimble is secured at the base of the case in a socket 81 82 whereby the same is permitted to vibrate upon a pin or a knife edge. The upper end of the thimbles are connected to the arm 91 92 which is suspended at a point V-J from the top of the oase by the hangers n a Figs. 2--, and permitted to vibrate upon a pin or a knife edge. The upper end of this arm is connected with a horizontal arm O1 O2 which connects with a vertical arm P1 P2, passing through the openings g g, and connected with the slide valve by means of the arm R R Fig. 2, which is of sufficient width to cover the openings g g and prevent the passage of water from without or within the case. By these two arms R'R with the arms P P connected with the slide valve, permanent each arm P, passing through. o-ne of the openings y Q into each compartment of the case and there co-nnected with a horizontal arm O1 O2 which connects with the arm L L, which is suspended from the top of the case at points adequatevto give the desired movement of the valve the lower end of this arm L L is connected with two thimbles one slipping within the other while one of them is secured to the base of the case in the socket joint 8 8 and permitted to vibrate upon al pin or knife edge by which arrangement when the slide valve is moved from left to right and vice versathe arms and thimbles in each compartment must move in concert, and the vibration coming upon the horizontal arms.y As the arm, L L is suspended from the case above and the thimble secured below, but permitted to vibrate the thimbles are permitted to work within themselves being connected to the lower end of the arm L L whereby that section of the connection may upon the movement of the valve be increased or diminished as the same is brought from the given angle to the vertical position and so vice versa. While the spiral spring, contracting in being brought to a vertical position by the thimbles shortening expands and throws the armsthereby moving the valve the balance of the stroke the moment the arm L L and thimbles are carried beyond the point of a direct vertical position.

The piston having comple-ted its stroke from left to right, and the valve changed covering the ingress passage II and egress one J-1eaving the passage I open thus the current of water passing through it, in the direction of the arrow causes the piston to traverse the cylinder toward the left while the water in front is forced out through the opening H into the passage J-thence out through the opening 5. Vhen near the completion of the stroke-it strikes the upper part of the thimble L at point S and forces the same over from the angle to a point beyond the vertical position as seen by the dotted lines moving the slide valve with it aided by the arms and changing the position of the arms and thimbles in the opposite compartment when the springs, having been contracted by the drawing together of the thimbles expands and throws the valve to its full length. When the passages I and J are covered leaving the passage H exposed to the pressure and passage of the .water from the valve chest into the compartment of the case causing the piston to move toward the right and vice versa at each and every stroke-both springs act-ing at once. In many kinds of meters owing to the great amount of sediment deposited whereby a slide valve would be soon made useless wicket and balanced puppet valves may be used to advantage and can be connected and used in this machine.

I/Vhat I claim, and wish to secure by Letters Patent, is-

A cylinder of any given size, with a ccmmon plunger within it, open at both ends and secured within a case divided into two compartments as above set forth-each com partment with their heads acting as heads to the cylinder and reservoirs to receive the sediment either drawn in and not thrown out or that which may be deposited from the water.

2. I claim the reservoir for the collection of sediment whether connected with a cylindrical or a rotary water meter.

8. I claim the mode of moving and throwing the valve as above set forth.

4. I claim the casting or turning of a groove upon the circumference of a piston plate and surrounded its entire diameter with holes drilled from the base of t-he same through on the inside in the manner and for the object set forth.

5. And lastly I claim the ent-ire combination for the object as above set forth.
